Question 1

Can the JavaScript call stack run two functions at the same time?

Accepted Answer

No. JS is single-threaded with one call stack, so only the top frame executes. Other calls must wait for the current one to return.

Question 2

What data structure is used by the Call Stack?

Accepted Answer

The Call Stack follows the Last-In-First-Out (LIFO) principle.

Question 3

Why is the Call Stack important?

Accepted Answer

It tracks function execution and execution contexts.

Question 4

Can the Call Stack overflow?
